>The variation in tandem repeats can also be detected as restriction fragment length polymorphisms, or RFLPs (DNA fragments of different sizes that had been cleaved by restriction enzymes). In the case of tandem repeats, a restriction enzyme cleaves the DNA flanking the repeat. Alternatively, resea..
